Therefore, I'm asking you all guys, if there is such a thing (for BTC or whatever other crypto currency), would you guys be interested in buying/using it? and why?

Thanks in advance for you all.

--Edit:
Here are some questions that we'd like you to answer in order to help us better shape the service:
1- Do you prefer a preset amount for each card? or would you like to charge it up to your liking?
2- Would you prefer a complete online order (even if it costs you slight privacy? specially when paying non-crypto like PP) or would you prefer to complete the deal at a shop with cash in hand and no personal info required?
3- If you answered 2 with completing at a shop, would you consider being a local distributor? why? and what would you expect in return?
4- Would you plan on buying larger quantities? continuous supply? or you just buy couple cards on special occasions and forget the service for the rest of the year? as this can affect the way to get local distributor.
5- Would you trust me/us/company to have the private keys in order to make things a bit easier at your end? or would you prefer spending extra couple minutes at your end to complete the deal without me/us/company having any way of touching the money in the card? note that this choice will affect the ability to recover the funds in case the card is lost, at the expense of storing some of your personal info, so this isn't for everyone.
6- Do you have expected shape/size/dimensions for the card? it might end up a bit larger than normal cards, but will make sure the space is well used.
7- What special occasions would you like to have the cards for? I'm not that cheerful person who remembers all occasions, the ones I have in mind right now are birthdays, x-mas and new year, not sure if you'd give bitcoin in valentine (there are more suitable coins for that Wink Wink)
